Wert einer JavaScript-Variable übergeben

[Simonvetterli]

Hallo Zusammen

Ich habe folgendes Problem und komme nicht weiter:

Folgendes JavaScript habe ich:

Code:

<script type='text/javascript'>
function calculate ()
{
var werta1 = document.getElementById('dsd013000').value;
var wertb1 = document.getElementById('dsd01').value;
var erg1 = werta1 * wertb1;
document.getElementById('erg1').innerHTML = erg1;
var werta2 = document.getElementById('sd014000').value;
var wertb2 = document.getElementById('sd01').value;
var erg2 = werta2 * wertb2;
document.getElementById('erg2').innerHTML = erg2;
var werta3 = document.getElementById('sd024000').value;
var wertb3 = document.getElementById('sd02').value;
var erg3 = werta3 * wertb3;
document.getElementById('erg3').innerHTML = erg3;
var werta4 = document.getElementById('dt0013000').value;
var wertb4 = document.getElementById('dt001').value;
var erg4 = werta4 * wertb4;
document.getElementById('erg4').innerHTML = erg4;
var werta5 = document.getElementById('dt0023000').value;
var wertb5 = document.getElementById('dt002').value;
var erg5 = werta5 * wertb5;
document.getElementById('erg5').innerHTML = erg5;
var werta6 = document.getElementById('owd0016000').value;
var wertb6 = document.getElementById('owd001').value;
var erg6 = werta6 * wertb6;
document.getElementById('erg6').innerHTML = erg6;
var werta7 = document.getElementById('aowd0016000').value;
var wertb7 = document.getElementById('aowd001').value;
var erg7 = werta7 * wertb7;
document.getElementById('erg7').innerHTML = erg7;
var werta8 = document.getElementById('efr0011000').value;
var wertb8 = document.getElementById('efr001').value;
var erg8 = werta8 * wertb8;
document.getElementById('erg8').innerHTML = erg8;
var werta9 = document.getElementById('resc0016000').value;
var wertb9 = document.getElementById('resc001').value;
var erg9 = werta9 * wertb9;
document.getElementById('erg9').innerHTML = erg9;
var werta10 = document.getElementById('sr0013000').value;
var wertb10 = document.getElementById('sr001').value;
var erg10 = werta10 * wertb10;
document.getElementById('erg10').innerHTML = erg10;

var summe = erg1 + erg2 + erg3 + erg4 + erg5 + erg6 + erg7 + erg8 + erg9 + erg10;
document.getElementById('sum').innerHTML = summe;

}
</script>

Die Variable "summe" möchte ich an folgendes Formular-Feld als Wert (value) übergeben:

HTML-Code:

<input type="hidden" id="subtotal" name="amount" value="die summe vom JavaScript">

HTML-Code:

<form action="https://www.paypal.com/cgi-bin/webscr" method="post">
  <input type="hidden" name="cmd" value="_cart">
  <input type="hidden" name="business" value="--------@--------">
  <input type="hidden" name="lc" value="<?php echo $lLC;?>">
  <input type="hidden" name="item_name" value="Diveservices Silent Divers">
  <input type="hidden" name="item_number" value="SilentDivers">
  <input type="hidden" name="button_subtype" value="services">
  <input type="hidden" name="no_note" value="20">
  <input type="hidden" name="currency_code" value="THB">
    <input type="hidden" id="subtotal" name="amount" value=<?$summe?>>
    <INPUT type="hidden" name=return value="http://www.--------.com/paythank.php">
  <input type="hidden" name="bn" value="PP-BuyNowBF:btn_buynowCC_LG.gif:NonHostedGuest">
  <input type="image" src="https://www.paypalobjects.com/en_US/i/btn/btn_buynowCC_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">
  <img alt="" border="0" src="https://www.paypalobjects.com/en_US/i/scr/pixel.gif" width="1" height="1">
</form>

Wer kann mir helfen, dies so schnell wie möglich zu machen?

Versuch mal:

document.getElementById('subtotal').value = summe;
